If you enjoyed Braid or puzzle games in general, I highly recommend you check this out. Great style and pretty original gameplay mechanics.
Considering it usually goes on sale for a little over $1 US during Steam sales, you can't really go wrong here. I first played this on the Xbox 360 many years ago, but wanted it on Steam too. I enjoyed it even more than I remembered.

I enjoyed Opus Magnum and Shenzhen I/O a bit more, but this is another solid Zachtronics game. If you liked Shenzhen, you'll like this one too. I think Opus Magnum is my favorite of the Zachtronics games that I've played so far.
